Can he even identify cyber targets?
"A recent documentary from BBC Radio 4 revealed that London Olympics officials were warned hours before the opening ceremony that the event might come under cyber-attack. Olympic cyber-security head Oliver Hoare was woken by a phone call from GCHQ at 04.15 on the day of the opening ceremony by GCHQ to warn of a credible threat to the "electricity infrastructure supporting the Games"."
If the electricity infrastructure is on a hackable public network, then you should sack the network admin that did that. Vague cyber-BS from GCHQ is just to give them cover for their own hacking.
The biggest threat of cyber hacking turns out to be GCHQ and NSA, just ask Belgacom. We made the mistake of giving them info on zero day exploits assuming they were within the legal framework of a democracy. Now we know better, they won't receive zero day exploits and Belgacom, Google, Vodafone Greece*, German telecoms, Spanish telecoms etc. are safer from hacking.
* Or was that even a hack? Now we know Vodafone was helping GCHQ spy on networks, did they also do that in Greece in 2002 and maybe even Spain? Why would you hack a company when you only need to ask?
Was Vodafone working for GCHQ back in 2002, when Merkel was bugged and when Vodafone Greece was found to be bugging Greek politicians, and even their spy chief?
